if you're a whale, then if you are an advocate of "this side" but then you also get inclined on "the other side", what would people think of you? they may think you're a "turncoat person" right? and then, when people think of you negatively, your power will be likely to diminish... you will get "unfollows"... then you will be a smaller fish... then you cannot support other minnows post greatly...
hope you get what I'm saying...
